This paper discusses the programming and control of a multi-cycle tape machine. Part of the electrical equipment is also presented. The program code in the language “Lader diagram” is selected and the input-output diagram is described. “Lader diagram” is a programming language designed to resemble an electrical circuit. Due to this fact, it has a great advantage over other programming languages, because electrical logic is easy and simple to present. Most of the programs in discrete automation are created on the “Lader Diagram” due to the simple operation and easy maintenance. The description and the cyclical approach of each executive body and automatic mode of operation are presented.
